Pectographic Study of Carbonate Sediments around Yewa River, Eastern Dahomey Basin, South Western Nigeria

Abstract: Limestone is the major component of carbonate sediments, and is usually deposited with the remains of skeletal fragments or marine organisms such as plants and microscopic animals as a result of both organic and inorganic processes. The associated minerals are:calcite, aragonite and dolomite minerals. The major ways of classification of limestone are based on its mineralogies, (allochems, cements, matrix) and texture (grain stone, packstone, mudstone, wackestone and boundstone). The topographic maps of Idogo NE, sheet 273NW of the study area includes adjoining communities around the North East and North West of River Igbin and south east of River Ogun, south of River yewa which drains in a sub dendiritic and dendiritic pattern and flows into the Yewa lagoon were studied and divided into grids of 500m intervals. Pitting exercise was carried out to expose the limestone beds after representative core samples were collected from labeled core boxes. Petrographic slides were prepared from seven limestone samples as a representative sample of borehole 4 borehole 5, borehole 7 borehole 9, borehole 10, borehole 13 and borehole 14 were prepared at the department of geology, Obafemi Awolowo University, Ile-Ife, the prepared slides from the collected samples were closely examined under plane polarized light.
